(b) Router has a number of film studios and office buildings. The office buildings are in prestigious areas whereas

the film studios are located in ‘out of town’ locations. The management of Router wish to apply the ‘revaluation

model’ to the office buildings and the ‘cost model’ to the film studios in the year ended 31 May 2007. At present

both types of buildings are valued using the ‘revaluation model’. One of the film studios has been converted to a

theme park. In this case only, the land and buildings on the park are leased on a single lease from a third party.

The lease term was 30 years in 1990. The lease of the land and buildings was classified as a finance lease even

though the financial statements purport to comply with IAS 17 ‘Leases’.

The terms of the lease were changed on 31 May 2007. Router is now going to terminate the lease early in 2015

in exchange for a payment of $10 million on 31 May 2007 and a reduction in the monthly lease payments.

Router intends to move from the site in 2015. The revised lease terms have not resulted in a change of

classification of the lease in the financial statements of Router. (10 marks)

Required:

Discuss how the above items should be dealt with in the group financial statements of Router for the year ended

31 May 2007.

The bank refused to ______him any money, so he had to postpone buying a house.

在Linux系统中配置DHCP服务器，该服务器配置文件的部分内容如下：

option touters 192.168.1.254；

option broadcast—address 192．168．1，255；

option domain—name—servers 192．168．1．3 ；

}

}

在主机webserver上运行ifconfig命令时显示如下，根据DHCP配置，填写空格中缺少的

内容。

该网段的网关IP地址为(7)，域名服务器IP地址为(8)。

请在(5)～(10)空白处填写恰当的内容。

在Linux系统中使用(5)程序提供DHCP服务，DHCP服务器启动时自动读它的配置文件(6)。DHCP服务器配置文件如下所示：

ddns-update-style. interim;

ignore client-updates;

default-lease-time 86400;

max-lease-time 129600;

subnet 192.168.0.0 netmask 255.255.255.0 {

option routers 192.168.0.1;

option subnet-mask 255.255.255.0;

option broadcast-address 192.168.0.255;

option domain-name-servers

61.233.9.9, 202.96.133.134;

range 192.168.0.10 192.168.0.250;

}

根据这个文件中的内容，该DHCP服务的默认租期是(7)天，DHCP客户机能获得的IP地址范围是；从(8)到(9)；获得的DNS服务器IP地址为(10)。

认真阅读下列有关Linux操作系统环境下配置一台DHCP服务器的说明信息，回答问题1、问题2、问题3、问题4和问题5。

[说明]

一台装有Linux操作系统的电脑，要在此电脑上配置一台DHCP服务器，主机名为CIU DHCP，IP地址为192.168.1.15，下面是其部分配置文件与语句。

在/etc/dhcpd.conf文件中有以下语句。

host CIU_DHCP{hardware ethemet 52.54.AB.3B.B6.45 fixed-address 192.168.1.15；}

subnet 192.168.1.0 netmask 255.255.255.0{range 192.168.1.10 192.168.1.253}

default-lease-time 600；

max-lease-time 14400；

option routers 192.168.1.10

optmn domain-name-servers 192.168.1.15

/etc/dhcpd.conf文件中的配置语句：

host CIU_DHCP{hardware ethemet 52.54.AB.3B.B6.45 fixed-address 192.168.1.15；}表示的是什么意思?

【问题3】（10分）

在Linux 系统中配置DHCP服务器，该服务器配置文件的部分内容如下：

subnet 192.168.1.0 netmask 255.255.255.0 {

option routers 192.168.1.254;

option subnet-mask 255.255.255.0;

option broadcast-address 192.168.1.255;

option domain-name-servers 192.168.1.3;

range 192.168.1.100 192.168.1.200;

default-lease-time 21600;

max-lease-time 43200;

host webserver {

hardware ethernet 52:54:AB:34:5B:09;

fixed-address 192.168.1.100;

}

}

在主机webserver 上运行ifconfig命令时显示如下，根据DHCP配置，填写空格中缺少的内容。

该网段的网关IP地址为 （7） ，域名服务器 IP地址为 （8） 。
